RUN N ING-GEAR FOR BOB-SLEDS.

Specification of Letters Patent. Application filed July 28, 1909. SerialNo.

Patented Aug. 30, 1910. 510,031.

To all whom it may concern:

Be it known that I, OSCAR C. SIMENSON, a citizen of the United States,and a resident of lVaukon, in the county of Allamakee and State of Iowa,have invented certain new and useful Improvements in Running-Gears forBob-Sleds, of which the following is a specification.

My invention relates to running-gears for double-runner bob-sleds, andhas for its obj ect the provision of means by which the reach-pole isconnected directly to the draftpole, and the rear runner secured bymeans of a draft-beam secured to the front ends of the runners to thereach-pole, the rear end of the reach-pole being slidably mounted in thebunk of the rear runners so that the pull on the rear runners is exertedat their front through the draft-beam aforesaid.

My invention will be described in detail hereinafter and illustrated inthe accompanying drawings, in whic Figure l is a side view of myimproved running-gear,- Fig. 2, a top plan View showin section; and Fig.3, a

ffbnt view and Fig. 4 a view in cross-section of the reach-pole anddraft-beam connected to the rear runners.

In the drawings similar reference characters indicate correspondingparts throughout all of the views.

1 indicates the front runners and 2 the rear runners of my improvedbob-sled, the front runners having the draft-pole 3 pivotally secured totheir front ends by crossrod 4 in the usual manner. The bunk 5 of thefront runner is formed with a central transverse groove 6, above whichis the bolster 7, swivelly mounted by means of kingpin 8.

9 indicates a link loosely mounted in groove 6 and connected by means ofrod 10 with a clevis 11, secured to the rear end of draft-pole 3. Thebunk 12 of the rear runners 2 is also formed with a transverse groove13, in which is slidably mounted the reach-pole 14, having its front endsecured to link 9 by means of U-shaped strap 15, having eye-loops 16 toreceive a bolt 17, secured through a hole in the front end of thereach-pole.

18 indicates a draft-beam secured to crossrod 19, swivelly secured tothe front ends of runners 2, 20 an eye-bolt secured in the front end ofsaid draft-beam, 21 a link engaging said eye-bolt 20 and mounted in slot22 in reach-pole l4, and 23 a pin engaging the link 21 to hold the linkin engagement with the slot aforesaid.

24 indicates the bolster on the rear runners 2, which are secured tobunk 12 in the usual manner.

18, secured to reachpole 1% by means of eye-bolt 20 and link 21, andthat the pull on the reach-pole is dilink 9, and U-shaped strap 15, andthat the advantage of this construction is that the rear runners arepulled over any obstructions that may be encountered in the road and thepull on the draft-pole lessened.

Having thus described my invention, what I claim is- A running-gear fordouble-runner bobsleds, consisting of front and rear runners, bunksmounted on said runners each having a transverse groove therein, aroller pivotally secured to the front runners the draftpole secured tothe roller, the reach pole slidably mounted in the groove in the rearbunk and formed with a vertical slot inter mediate of its ends, a rollersecured to the front ends of the rear runners a draft-bean1 secured tosaid roller, an eye-bolt secured to the free end of said draft-beam, alink secured to said eye-bolt and mounted in the slot on the reach-pole,a pin engaging said link and the top of the reach-pole, a link mountedin the groove in the front bunk and pivotally secured to the front endof the reaclrpole, and a rod pivotally secured to the last-mentionedlink and to the draftpole, substantially as shown and described.

In witness whereof, I have hereunto set my hand in presence of twosubscribing wit- I nesses.
